Neither as long nor as wide as Derek Cohen's, but still pretty hefty:
24” long jointer, bedded at 45 degrees. The iron is a LV woodie, 2 3/8” wide.
Beech body with ipe sole. The tote is cherry, knob is jatoba. Finish is tung oil.
The knob is threaded in so I can remove it easily. Without the knob, I find it hard to get a good grip for planing or lifting it, so I just leave the knob on.
I must admit that I’m not a hand plane purist. If I need to joint something in earnest, the machine jointer is nearly always my first choice. This does come in handy, though, on parts that would be too small or unsafe in other ways to machine joint, like I had to do in my workbench build. It is also handy to match plane two wide-ish edges in preparation for gluing. Because of this, I left the mouth with a very fine opening, nearly as small as a smoother’s.
